Why it matters

### Layered protection, without the enterprise overhead.

Attackers target smaller businesses because they expect thinner defenses. GFI security products cover the main ways in, from the network perimeter and unpatched devices to the inbox, and each one is built to deploy and manage without a specialist team.

#### The perimeter

Next-generation firewall, IPS, VPN and web filtering.

#### Every device

Find vulnerabilities and patch them across Windows, macOS and Linux.

#### The inbox

Stop spam, phishing and malware before they reach users.

The GFI security portfolio

### Three products. Every major entry point covered.

#### GFI KerioControl
